Dark Energy Camera (DECam) installation. The DECam prime focus cage under the Blanco 4-metre telescope undergoing tests and awaiting installation at the Cerro Tololo Inter-American Observatory (CTIO) in Chile. The DECam is used by the Dark Energy Survey (DES) to record red light from distant galaxies, finding large-scale patterns and structure relating to dark energy, the phenomenon that is accelerating the expansion of the universe. This is a tone-mapped, high-dynamic range image constructed of several photographs combined. Installation of DECam took place in 2012. | |
